Christchurch looks to be in for another spate of good-news announcements after recent hints by recovery leaders.

The rebuild of the earthquake-destroyed city centre has accelerated in the last two months. Vodafone has announced it would anchor the innovation precinct and the Music Centre of Christchurch confirmed it would build in the performing arts precinct.

The Carter Group recently kickstarted the provision of car parking near the city's retail core and Re:Start Mall has relocated to make way for Nick Hunt's $100 million Cashel Square development.

Last week Brownlee said: "We can look forward to some announcements very shortly" on progress with the Convention Centre.

Speaking at the reopening of Re:Start Mall, Brownlee said he also expected more news about innovation precinct developments in the coming months.

"And over the next couple of years, we're going to see a whole lot of investment . . . some [projects] I'm aware of already but I can't talk about just now," he said.

Prime Minister John Key was in Christchurch last week and said momentum was starting to build in the recovery.

"If you look at the development . . . ultimately in the CBD area, it's starting to progress quite well and the sense I get being down here is there's quite a lot of confidence coming from Cantabrians now."

He said Vodafone's announcement was "quite significant".

"And you're starting to see a number of other developers . . . telling me they have big plans for announcements very soon," he said.

Christchurch Central Development Unit director Warwick Isaacs said he could not provide "any detail ahead of any upcoming announcements" but confirmed more positive developments for Christchurch were in the works.
